Yoko Ono is a Japanese artist, musician, author and peace activist, known for her work in avant-garde art, music and filmmaking as well as her marriage to John Lennon.

Yoko Ono was born on February 18, 1933, in Tokyo, Japan, the eldest of three children born to Eisuke and Isoko, a wealthy aristocratic family. Her father, who worked for the Yokohama Specie Bank, was transferred to San Francisco two weeks before she was born. The rest of the family soon followed. Her father was transferred back to Japan in 1937, and she enrolled at the elite Peers’ School in Tokyo.

In 1940, the family moved to New York, then back to Japan in 1941 when her father was transferred to Hanoi on the eve of the Japanese attack on Pearl Harbor. Ono remained in Tokyo through World War II, including the great-fire bombing of 1945. At age 18, Ono moved with her parents to Scarsdale, New York. She studied at Sarah Lawrence College, but left to elope with her first husband, Toshi Ichiyanagi.

Settling in Greenwich Village, she developed her interest in art and also began writing poetry. Considered too radical by many, her work was not well received but she gained recognition after working with American jazz musician/film producer Anthony Cox, who later became her second husband. Cox financed and helped coordinate her "interactive conceptual events" in the early 1960s. Yoko's work often demands the viewers' participation and forces them to get involved. Her most famous piece was the "cut piece" staged in 1964, where the audience was invited to cut off pieces of her clothing until she was naked, an abstract commentary on discarding materialism.

Ono first met John Lennon of the English rock band The Beatles November 9, 1966, when he visited a preview of her exhibition at the Indica Gallery in London. He was taken with the positive, interactive nature of her work. He especially cited a ladder leading up to a black canvas with a spyglass on a chain, which revealed the word “yes’ written on the ceiling
